It's been enough time that i can have a laugh at myself. Shitting yourself as an adult is terrible when it happens, but now I can look back on it and laugh a little.
When it happened I was 20, I won't go into it exactly but I was crippled at the time. Back brace that covered my body to stabilize a vertebra and a guard that covered my broken wrist. I'm in the middle of my Statistics class on the third floor in uni and halfway through I feel that rumble, you know, the one deep in the pit of your stomach that means nothing but trouble

. The worst kind too, the one that happens and you
immediately know "shit, i have to do something about this ASAP or i'm done".
So in this semi handi-capable state i get up and hobble to the bathroom on the third floor. I'm doing those wobbly ass clench walks, because i know that if i take
one single misstep a putrid shitblast will erupt from my numb, nerve damaged buttocks. By the time i actually make it to the bathroom i'm about to burst. I make it inside the stall, and i attempt the maneuver; you know the one, where you sit down and pull your pants down in one fell swoop.
My jeans got stuck on my back brace and i release a shotgun blast of diarrhea all over the lip of the toilet, the seat, inside jeans and the boxer briefs inside of them. I just stooped there a minute over this ruined toilet stall thinking, "damn, what the hell should I do with this". I wiped my ass first of course. Then in this painful pose i take my jeans off, clean the outside of them, throw away the boxers, and hope to god no one comes into this semi public bathroom. I made a feeble attempt at cleaning the rim of the toilet at least, i figure its the least i can do for whatever janitor whose day i just ruined.

I hobble back to my room, jeans subtly stained in shit, keeping a 20 yard distance from anyone who could possibly realize i had just shit myself. Took a shower, threw my clothes in the wash, and then walked back to class (which I knew was over) to get my stuff. I catch my teacher on the way out and i'm formulating an excuse. She says "when students leave like that i know not to ask any questions."
